Recovery of deleted files for BSD
FreeBSD is an operating system for modern server, desktop and embedded computer platforms. UFS/UFS2 are native file systems for FreeBSD, though presently FreeBSD is inheriting the ZFS file system of Sun Solaris.
The UFS/UFS2 system gives modest chances for recovery of deleted files. Deleting a file, UFS/UFS2 clears the information part of file node and updates tree of free blocks. Thus, the information about file name is unlinked from the directory entry. At the same time, the system doesn't employ journalizing that substantially complicates deleted files recovery.
SysDev Laboratories offers UFS Explorer, Recovery Explorer and Raise Data Recovery for efficient data recovery from the UFS file system.
